MORE-KARE

Background


Over half a million adults in the UK have a severe alcohol use disorder that requires treatment1. However, only 1 in 5 of these individuals access treatment – and current treatments show low success rates in stopping relapse in the long term2. Research suggests that ketamine may be useful in the treatment of alcohol use disorder3. Early research conducted in the 1980s found promising reductions in alcohol relapse rates following ketamine treatment4. Studies have also shown that ketamine has a fast-acting anti-depressant effect and may improve learning of new information – both of which may help prevent relapse in alcohol use disorder3,5.

MORE-KARE will build on the findings of the previous KARE trial 6. In this trial, three doses of ketamine given alongside seven sessions of therapy increased abstinence from alcohol by 16% compared with placebo (i.e. no treatment).
